The refrigerant used in the system is R-22. It is clear, color-
less, nontoxic, nonirritating, and nonexplosive liquid. The
chemical formula is CHCLF
2
. The boiling point, at atmospheric
pressure is -41.4°F.
A few of the important principles that make the refrigeration
cycle possible are: heat always flows from a warmer to a
cooler body, under lower pressure a refrigerant will absorb
heat and vaporize at a low temperature, the vapors may be
drawn off and condensed at a higher pressure and tempera-
ture to be used again.
